GDLS PERCH System Debuts at AUSA 2025 to Equip M1A2 Abrams with Loitering Munitions

At AUSA 2025, General Dynamics Land Systems (GDLS) introduced the PERCH system—a modular launcher designed to integrate loitering munitions directly onto M1A2 SEPv3 Abrams main battle tanks. This innovation signals a new phase in armored warfare by enabling tanks to conduct over-the-horizon reconnaissance and precision strikes using expendable drones.

PERCH Concept: Extending the Reach of Armored Formations

The PERCH (Platform Extension for Robotics and Command Host) is a modular drone launch-and-control system designed specifically for integration on armored platforms such as the M1A2 SEPv3 Abrams. The concept was developed by GDLS in response to emerging battlefield requirements for enhanced situational awareness and organic precision fires at the platoon level.

Mounted on the turret bustle of the tank or potentially other armored vehicles like Stryker or optionally manned fighting vehicles (OMFV), PERCH provides a self-contained capability to launch and control small unmanned aerial systems (sUAS) including loitering munitions. The system includes:

A retractable launcher pod capable of deploying multiple types of drones
A ruggedized control station integrated into the vehicle’s C4ISR suite
Data links for real-time video feed and targeting updates

PERCH is designed to be platform-agnostic and modular—allowing different classes of loitering munitions or ISR drones depending on mission needs. At AUSA 2025, GDLS demonstrated compatibility with AeroVironment’s Switchblade series and Shield AI’s V-BAT 128 vertical takeoff drone.

Operational Rationale: Bridging ISR Gaps for Armored Units

The U.S. Army’s push toward multi-domain operations (MDO) has highlighted a critical gap in organic ISR (intelligence, surveillance, reconnaissance) and precision strike capabilities at the tactical edge. While larger UAVs provide theater-level coverage, frontline units often lack persistent situational awareness beyond line-of-sight.

By integrating loitering munition capabilities directly onto armored vehicles via PERCH, tank crews can:

Conduct reconnaissance-in-force without exposing themselves to ambushes
Identify enemy armor or ATGM teams before line-of-sight contact
Deliver precision effects against soft-skinned or dismounted threats beyond direct fire range

This aligns with lessons learned from recent conflicts—particularly Ukraine—where FPV drones and loitering munitions have proven decisive in shaping maneuver corridors and suppressing anti-tank threats. The ability for an Abrams crew to autonomously deploy a Switchblade or V-BAT provides a significant tactical edge.

Compatible Loitering Munition Payloads

The initial demonstration featured two primary drone types compatible with PERCH:

AeroVironment Switchblade Series

The Switchblade family—particularly the Switchblade 300 Block 20—is a man-portable loitering munition optimized for soft targets up to ~10 km away. Weighing under 3 kg with an EO/IR seeker and anti-personnel warhead, it offers rapid deployment via tube launch. Integration into PERCH allows armored crews to launch these kamikaze drones without dismounting.

Shield AI V-BAT 128

The V-BAT is a Group III vertical takeoff drone capable of hovering flight and extended endurance (~8+ hours). With a max takeoff weight around 56 kg, it supports EO/IR payloads for persistent ISR missions. While not a kinetic munition itself in current configurations, its use from tanks enables overwatch during urban maneuver or convoy security operations.

Future variants may include heavier payloads or even kinetic options if paired with third-party warheads or modified airframes.

Tactical Implications Across Army Formations

If fielded broadly across ABCTs (Armored Brigade Combat Teams), PERCH could significantly alter how U.S. armor operates in contested environments:

Maneuver autonomy: Units gain organic eyes-on-target before cresting terrain features or entering kill zones.
Saturation targeting: Multiple tanks could simultaneously deploy loitering munitions against enemy positions from standoff range.
C4ISR fusion: Real-time feeds from launched drones can be networked across formations via IVAS systems or tactical cloud nodes.

This would enhance survivability against ATGMs by allowing preemptive strikes on firing positions while also reducing reliance on external UAV support assets that may be unavailable during high-tempo operations.

Status, Roadmap & Integration Challenges

The version shown at AUSA remains a technology demonstrator; no formal program-of-record exists yet within PEO Ground Combat Systems as of October 2025. However, GDLS officials stated that discussions are underway with Army Futures Command regarding potential experimentation under Project Convergence pathways.

Key challenges ahead include:

Crew workload management: Integrating drone control into existing fire control interfaces without overloading operators will require UI/UX refinement.
Spectrum deconfliction: Ensuring secure data links that do not interfere with other battlefield comms systems is critical for survivability in EW-contested domains.
MRO/logistics: Sustainment models must account for expendable payload resupply at company/platoon level if these become routine tools.

If successful in trials over FY26–27, PERCH could be fielded as early as FY28 alongside planned upgrades under the M1E3 program which aims to reduce weight while improving digital architecture compatibility for emerging technologies like autonomy modules and active protection systems (APS).

A Glimpse into Future Combined Arms Warfare

The unveiling of PERCH underscores how traditional force multipliers like heavy armor are evolving into sensor-shooter nodes within larger tactical networks. By fusing mobility, protection, firepower—and now aerial reach—the Abrams platform remains relevant amid shifting threat environments characterized by distributed lethality and low-cost drone saturation tactics.

If adopted at scale across NATO forces or allied MBTs such as Leopard 2A7+ or Challenger III equivalents via similar modular kits, this could redefine how armored formations engage peer adversaries equipped with layered anti-access/area-denial (A2/AD) defenses.
